摘要： A compressor provided with a torque limiter constructed such that, in view of possible occurrence of accidental locking of the compressor, in the case where a one-way clutch is used in place of an electromagnetic clutch in order to permit a refrigerant compressor for a vehicle air-conditioning system to be driven by an electric motor instead of an internal combustion engine, when an excessive torque is to be transmitted by the one-way clutch, rollers ride over wedge surfaces and fall into pocket sections, or sprags are reversed to roll-over.

摘要： A power transmission device includes a first one-way clutch that transmits a rotational power of a pulley to a rotating shaft, and a second one-way clutch that transmits a rotational power of a rotor of a motor to the rotating shaft. The first one-way clutch is of inner cam type in which an engagement cam-surface is formed in an outer periphery of a first inner ring, while the second one-way clutch is of outer cam type in which an engagement cam-surface is formed in an inner periphery of a second outer ring. This arrangement improves engagement performance of the first one-way clutch as well as reducing heat generation of the second one-way clutch, so that the lifetime of grease is prolonged.

摘要： There is provided a one-way clutch unit that is simple in structure and compact. An annular recess 67 is provided in an inner periphery of a side of a deep groove ball bearing portion 55 of a first inner ring 7 of a first one-way clutch 1, and an end portion on the side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in the annular recess 67. Thereby, the dimension in an axial direction of the one-way clutch unit is reduced by a dimension in the axial direction of the second one-way clutch 2 that is disposed in the annular recess 67.

摘要： There is provided a compact one-way clutch unit that can perform connection and disconnection of power in two systems. An end portion on a side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in an annular recess 67, which is provided at an end portion in an inner peripheral surface of a first inner ring 7, so that the dimension in an axial direction of a one-way clutch unit is reduced. Further, an outer peripheral diameter on a side of the deep groove ball bearing portion 65 is made smaller than that on the side of a one-way clutch portion 60 of a second outer ring 14 so as to reduce a diameter of the recess 67 and the outer peripheral diameter of the first outer ring 5 of the first one-way clutch 1.

摘要： A housing of an electric motor includes an inner circumferential surface, which includes recesses arranged along the circumferential direction. On an outer circumferential surface of a stator core of a stator are provided protrusions arranged along the circumferential direction. Fitting each protrusion to the corresponding recess fixes the stator core to the housing. A rotor is provided radially inward of the stator. In a state where each protrusion is fitted to the corresponding recess, a pair of side surfaces of each protrusion are retained by a pair of inner side surfaces of the corresponding recess in the circumferential direction of the housing. A gap is formed between an end face of each protrusion and an inner bottom surface of the corresponding recess facing the end face along the entire surface of the end face.

摘要： Outer circumference of a rotor is alternately provided with a plurality of circumferential portions and a plurality of convex portions. Straight lines each connecting a rotational axis to one of circumferential centers of circumferential portions are referred to as radial lines. Straight lines each bisecting one of convex portions are referred to as bisectors. A plurality of magnetic flux blocking regions are located on a rotor. One of the magnetic flux blocking region is located in a range between the radial line and the bisector adjacent to and preceding the radial line in the rotation direction. Therefore, a permanent magnet embedment rotating electric machine is capable of preventing decreases in torque and suppressing torque ripple.
